The genetic control of platelet production and function

Funded Activity Summary

Platelets are the tiny cells that circulate in the body and make blood clot. The human body has more than a trillion of them at any one time, and they are replaced every week by the blood producing cells that reside in the bone marrow. Keeping the normal number of platelets steady is incredibly important any significant drop can result in a life-threatening hemorrhage. The clinical name given to a low platelet count is thrombocytopenia, and it is a very common problem. It can be caused by genetic mutations, viral infections, or by cancer treatments like chemotherapy. The only way to raise platelet numbers in a person with thrombocytopenia is a blood transfusion, which carries with it risks and potential side effects. While we understand quite a lot about how the body produces platelets, we don t know anywhere enough to be able to develop new treatments. Our work is focused on the identification of the genes that control the process, beginning with mouse models of thrombocytopenia, genome mapping, gene isolation, and finally, making the links between the newly identified genes and patients with thrombocytopenia. It will give us a much better understanding of how platelets are produced, how things go wrong in human disease, and how new therapies might be developed to treat them.
